Title: Rewriting device for reversible display medium
Inventor: SAITO RITSU
IPC: G02F1/13
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent charge-up from occurring when a display state is changed by electric field, by applying AC voltage with an electric field applying means functioning as a changing means. SOLUTION: A PDLC reversible display medium 100 is composed of base material, a conductive layer, a PDLC film and a protection layer, A heat roller 1 and two parallel conductive rollers 2 are arranged to come in contact with the medium 100 from the protection layer side, and the roller 1 is rotated in synchronization with the movement of the medium 100 and preheats to soften the medium 100, whereby liquid crystal and dichroic coloring matter are easily oriented. The rollers 2 are set so that their diameter may be 15 mm, they may be arranged at interval of 18 mm, and AC may be applied to them by an AC power source 3 so as to generate the AC electric field in the PDLC film, whereby the liquid crystal is oriented and display is erased.  It is desirable to set the frequency of AC to 5 Hz to 10 kHz because the charge-up occurs when the frequency is too low and temperature rises due to dielectric heating when it is too high.

Title: Detection equipment of substrate in substrate accommodating vessel
Inventor: AZUMA AKIHIRO
IPC: H01L21/66
Filed: 1991-08-09
Abstract: PURPOSE:To detect whether substrate exist in a substrate accommodating vessel, by quickly handling the case even when a vessel with different substrate accommodation pitch is set. CONSTITUTION:An optical sensor elevating mechanism 25 continuously moves an optical sensor for detecting a substrate, along a substrate accommodating vessel. A pitch member 30 moves together with the optical sensor elevating mechanism 25, and a timing detection sensor 32 detects slits 31 of the pitch member 30 and intermittently outputs a timing signal. The slits 31 are arranged at a pitch shown by the greatest common measure of trench pitches of substrate accommodating vessels having different kinds of specifications. A CPU counts the timing signal while referring trench pitch information of the substrate accommodating vessel set by a pitch information setting apparatus. When the counted value coincides with a value corresponding to the trench pitch information, the CPU takes in the output from the optical sensor, and detects whether substrates exist.

CONSTITUTION:Through a relation action between a valve 5 for feeding a pressure and a valve 3 for discharging an over pressure, a specified pressure in a pressure feed pipe A is automatically fed to a pressure chamber B to ensure a desired minimum pressure in the pressure chamber B. An over pressure exceeding a set pressure in the pressure chamber B is automatically discharged to a discharge system to set a desired maximum pressure in the pressure chamber B. A pressure Pb in the pressure chamber is automatically controlled in a given range, and a fluctuation in a pressure in the pressure chamber is not propagated in a pressure feed chamber. A maximum pressure control range in the pressure chamber is regulated through the energizing forces of springs 4 and 6.

Filed: 1994-09-20
Abstract: PURPOSE: To remove particles captured above a wafer from a wafer treatment chamber during treatment by letting the particles above the wafer freely flow out under a peripheral mechanism and freely discharging them from the chamber. CONSTITUTION: Before disconnecting high-frequency power from a chamber electrode 16 at the time of treatment completion, the flow of all cooling gas to be supplied to a wafer 22 is stopped, and a clamp mechanism 24 and a focus ring 28 are moved up from the wafer 22. Then, the particles captured above the wafer 22 during treatment are let flow out of the downside of clamp mechanism 24 and focus ring 28 and discharged through an exhaust port 26. It is suitable that the supply of gas is switched to an inert gas, before moving the clamp mechanism 28 upwards and a gas flow rate is improved so as to surely discharge the particles into the exhaust port 26. Thus, the level of particle contamination due to the storage of captured particles during treatment can be practically decreased.

Title: Input buffer circuit
Inventor: SASAKI MASAYUKI
IPC: H03K19/0175
Filed: 1988-09-09
Abstract: PURPOSE:To simplify the design and to reduce the cost by accepting an inputted CMOS level and an inputted TTL level by an input buffer section. CONSTITUTION:An input level detected by a NOR gate 3 is set to a CMOS level and an input level detected by a NAND gate 4 is set to a TTL level respectively. When the CMOS level is used for the input terminal, the signal of the CMOS level is detected by a NOR gate 3 only. When the TTL level is inputted, its high level is detected by the NAND gate 4 and the high level being the TTL level as the intermediate level is not affected on the NOR gate 3 detecting the CMOS level. Thus, two kinds of input buffers are not required and since one kind of the buffer is enough, the design cost is reduced.

Abstract: PROBLEM TO BE SOLVED: To utilize the elastic deformation of a valve element part by pressure, and improve sealed properties when a valve is closed, by forming the valve element part of a flexible material such as resin or rubber together with an insertion part and a pulling out preventing part. SOLUTION: A valve hole 61 having a predetermined inside diametral dimension (a) and length (b), is arranged in a casing 51, and a check valve is so formed that an insertion part 1, a valve element part 2 and a pulling out preventing part 3 are integrally formed like a pin, comprising resin as a forming material, and inserted and mounted downward from an upper part in the valve hole 61.
